Went to "Threaded Rods": 1/4-20 is $1.90/ft, but 10-32 is _$16.90_ a
foot!!??! WTF? 9 times as much?

Are you reading that right?

What I see at $16.90 is labeled ".10-24" or 1/10"-24, based on
the ".25-20" being 1/4"-20

And later on I see ".10-32" (1/10" 32) at $15.11

These are almost certainly rolled threads, and it may be more
difficult to roll clean threads at that small a diameter.

I do see one about 3/4 of the way down the page which is clearly
labeled "10-32" and is 304 SS, not the chrome molly steel of the earlier
ones. If it were not for seeing this, I would think that the ".10-24"
and ".10-32" were entered by someone who does not understand screw
sizing. But ".25-28" is clearly 1/4-28.

I think that if you are that interested, you should call them
and talk to someone who can be clear about the sizes. :-)

Enjoy,
DoN.
